Thanks to everyone who responded. I think Giorgos' suggestion to move
away from a shell script was the most elegant one, and I rewrote my
script in Python (plagiarizing most of his code in the meantime) and it
works great.

Ironically, it runs even faster than the /bin/sh + find(1) version,
go figure.

Thanks again,
Alex
